  FIG. 1 shows a portable device 100 according to the present embodiment.

  The portable device 100 according to the present embodiment is used in a passive keyless entry (PKE) system that switches and controls locking / unlocking of an automobile door, and a portable device unit 110 is accommodated in a case 120. It has the structure made. The portable device 100 according to the present embodiment has, for example, an outer diameter of 40 to 55 mm (preferably 46 to 53 mm) and a thickness of 10 to 18 mm (preferably 14 to 16 mm).

  FIG. 2 shows the portable unit 110.

  The unit 110 for portable devices has a configuration in which the battery holder 20 is provided so as to overlap the circuit board 10 to form a laminate, and the laminate 40 is covered with the integrated member 40.

  3A and 3B show the circuit board 10.

  The circuit board 10 has a circular outer shape, and is formed with semicircular first to third defect portions 11a, 11b, and 11c at intervals in the circumferential direction. With reference to the substrate center of the circuit board 10, the angular interval from the first defect portion 11a to the second defect portion 11b is 90 °, the angular interval from the second defect portion 11b to the third defect portion 11c is 135 °, and The angular interval from the third defect portion 11c to the first defect portion 11a is also 135 °. For example, the circuit board 10 has an outer diameter of 20 mm to 30 mm (preferably 24 mm to 26 mm) and a thickness of 0.5 mm to 1.5 mm (preferably 0.8 mm to 1.0 mm). If the thickness is less than 0.5 mm, warping tends to occur or undesired breakage tends to occur, and if it exceeds 1.5 mm, the thickness tends to be unsuitable for thinning and miniaturization.

  The circuit board 10 has a wiring surface on one side, wiring is provided on the wiring surface, and an insulating film is coated on the surface so as to cover the wiring. The circuit board 10 has an element mounting surface on the other side, and various electronic elements 12 are mounted on the element mounting surface. In addition, wiring may be provided as appropriate on the element mounting surface on the other side, and the circuit board 10 can be downsized by adopting such a configuration.

  In the circuit board 10, the first antenna 13 a (X-axis antenna) extends in a direction orthogonal to the direction connecting the first defect portion 11 a and the substrate center, slightly toward the substrate center side from the first defect portion 11 a on the wiring surface. The second antenna 13b (Y-axis antenna) extends in a direction orthogonal to the direction connecting the second defect portion 11b and the substrate center, slightly toward the substrate center side from the second defect portion 11b. Is provided. Therefore, the first antenna 13a of the X-axis antenna and the second antenna 13b of the Y-axis antenna are provided so that the axial directions (directions shown in FIG. 3) are substantially orthogonal. For example, the first antenna 13a and the second antenna 13b are formed by winding an antenna wire such as a copper wire, a copper alloy wire, an aluminum wire, an aluminum alloy wire along a specific axis, and an antenna wire on a magnetic core (magnet). It is composed of a wound one, or one having these structures sealed with a resin or rubber insulating material.

  The circuit board 10 is provided with a negative electrode terminal 14 (battery electrode) slightly on the substrate center side from the third defect portion 11c on the wiring surface, and a positive electrode terminal 15 between the negative electrode terminal 14 and the second antenna 13b. (Battery electrode) is provided. The negative electrode terminal 14 is composed of a leaf spring-shaped metal piece, and extends obliquely so that the plate surface is inclined with respect to the circuit board 10 from both sides of the dumbbell-shaped board connection end. It is formed in an open V shape. The positive electrode terminal 15 is also made of a plate spring-like metal piece, has a substrate connection end on the opposite side of the second antenna 13b from the first antenna 13a side, and subsequently the plate surface faces the circuit board 10. And in a plan view, it is formed in a “<” shape that extends toward the second antenna 13b and then bends and extends toward the first antenna 13a.

  In the circuit board 10, pin terminal insertion holes 16 are formed on both sides in the length direction of the first antenna 13a. Further, the circuit board 10 has a first antenna in the length direction of the second antenna 13b slightly from the pin center insertion hole 16 on the side opposite to the second antenna 13b side in the length direction of the first antenna 13a. An inspection hole 17 is formed on each side opposite to the 13a side.

  4A to 4C show the battery holder 20.

  The battery holder 20 is made of, for example, a thermoplastic resin such as ABS resin (acrylonitrile / Butadiene / Styrene copolymer synthetic resin), PBT resin (polybutylene terephthalate resin). It is preferable. Of these, PBT resin is preferred because it is excellent in heat resistance (not deteriorated in a soldering process described later).

  The battery holder 20 has the same circular outer shape as the circuit board 10 and is formed in a bottomed cylindrical shape opened on one side, and both sides in the thickness direction are formed in a bowl shape and are formed on the outer peripheral edge. A groove 21 having a U-shaped cross section is formed to form a bobbin. The thickness (H in FIG. 4B) of the main body portion of the battery holder 20 is, for example, 5 to 12 mm. The cross-sectional shape of the groove 21 may be U-shaped.

  The battery holder 20 is semicircular at intervals in the circumferential direction so as to correspond to the first to third chipped portions 11a, 11b, and 11c of the circuit board 10 on the end surface portion on the opening side, that is, the outer peripheral portion. Shaped first to third positioning protrusions 22a, 22b, and 22c are projected.

  In the battery holder 20, a battery accommodating portion 23 for a circular battery button battery B is formed at the bottom opposite to the opening side so as to correspond to the negative electrode terminal 14 and the positive electrode terminal 15 of the circuit board 10. Yes. In addition to the portion corresponding to the positive electrode terminal 15, the battery housing portion 23 is provided with an inner wall 23 a and a battery support portion 23 b formed so as to protrude inward and extend in an arc shape. The battery support portion 23b is formed in a U-shaped cross section that opens to the circuit board 10 side, and an interference prevention defect 23c is formed in a portion corresponding to the negative electrode terminal 14. Thus, the portion corresponding to the positive electrode terminal 15 of the battery housing portion 23 does not have the inner wall 23a and the battery support portion 23b, and the battery support portion 23b is formed in a U-shaped cross section. Since the interference prevention defect 23c is formed in the portion corresponding to the above, unnecessary portions are omitted, and the weight of the battery holder 20 is reduced.

  The first to third engaging protrusions 24a, 24b, and 24c are integrally formed at the peripheral edge of the opening end of the battery housing portion 23 with an angular interval of 120 ° in the circumferential direction with respect to the center of the battery housing portion 23. Projected. Of these first to third engagement protrusions 24a, 24b, and 24c, the first engagement protrusion 24a on the center side is relatively large and is formed in a disk shape, which is the opening of the battery housing portion 23. Each of the second and third engagement protrusions 24b and 24c on the outer peripheral side is relatively small and has a hook-shaped engagement claw at the tip. It is formed in a plate shape, and the engaging claw is erected so as to protrude slightly inward from the opening end of the battery housing portion 23.

  The battery holder 20 has a portion protruding in a triangular shape on the inside so as to correspond to each of the pair of pin terminal insertion holes 16 of the circuit board 10, and a pin terminal insertion hole 25 is formed in that portion. Yes. The battery holder 20 is formed with a U-shaped engraved portion 26 opened outward corresponding to each of the pair of pin terminal insertion holes 25 on the surface side of the bottom portion, and the pair of pin terminal insertion holes 25. An alignment mark 27 made up of, for example, an isosceles triangular protrusion having an outward apex angle is provided in the center of the space. Further, the battery holder 20 has a normal circuit of the portable unit 110 (mobile device 100) by inserting an inspection pin into the bottom so as to correspond to each of the pair of inspection holes 17 of the circuit board 10. An inspection hole 28 for inspecting whether or not is formed.

  FIGS. 5A and 5B and FIG. 6 show a laminate of the circuit board 10 and the battery holder 20. Note that the Z-axis direction shown in FIG. 6 is a direction perpendicular to the XY plane (X-axis direction, Y-axis direction) described above.

  The circuit board 10 and the battery holder 20 are overlapped so that the wiring surface side of the circuit board 10 and the opening side of the battery holder 20 face each other, and the first to third defective portions 11a and 11b of the circuit board 10 are overlapped. , 11c are positioned so that the first to third positioning protrusions 22a, 22b, 22c of the battery holder 20 are engaged with each other to constitute a laminated body. Thus, the first and second antennas 13a and 13b of the circuit board 10 are covered by the bottom, and the space in which the first and second antennas 13a and 13b are accommodated is partitioned from the battery accommodating part 23 by the inner wall 23a. Furthermore, the negative electrode terminal 14 is exposed from the bottom of the battery housing portion 23, the positive electrode terminal 15 is exposed from a portion of the battery housing portion 23 that does not have the inner wall 23 a, and the pin terminals of the circuit board 10 and the battery holder 20 The insertion holes 16 and 25 communicate with each other, and the circuit board 10 and the inspection hole 28 of the battery holder 20 are aligned.

  Here, since the 1st-3rd defect | deletion part 11a, 11b, 11c and the 1st-3rd positioning protrusion 22a, 22b, 22c are formed in semicircle shape, the component mounting area | region of the circuit board 10 and the battery holder 20 Can be secured widely.

  In addition, with reference to the substrate center of the circuit board 10 or the holder center of the battery holder 20, the second defect portion 11 b and the second positioning protrusion 22 b of the second defect portion 11 b and the second positioning protrusion 22 b are moved from the first engagement position of the first defect portion 11 a and the first positioning protrusion 22 a. Since the angle interval to the second engagement position is 90 °, the visibility of the first and second engagement positions is good, and the workability when mounting the battery holder 20 on the circuit board 10 is excellent. In addition, the angular interval from the second engagement position of the second defect portion 11b and the second positioning protrusion 22b to the third engagement position of the third defect portion 11c and the third positioning protrusion 22c is 135 °, and similarly the third defect Since the angular interval from the third engagement position of the portion 11c and the third positioning protrusion 22c to the first engagement position of the first defect portion 11a and the first positioning protrusion 22a is also 135 °, the defect portion and the positioning protrusion In the wrong combination, three sets of engagement structures are not configured, and from this point, workability when mounting the battery holder 20 on the circuit board 10 is excellent. The mounting state in which the battery holder 20 is overlaid on the circuit board 10 has a structure that is highly stable and has little variation as a whole, including appearance and electrical characteristics. In addition, when it is going to mount so that the element mounting surface side of the circuit board 10 may oppose the battery holder 20, or when it is going to mount so that the bottom side of the battery holder 20 may face the circuit board 10, The laminated body of the circuit board 10 and the battery holder 20 is impossible due to interference.

  In the laminated body of the circuit board 10 and the battery holder 20, an antenna wire is wound around the groove 21 on the outer peripheral edge of the battery holder 20 to form a third antenna 29 formed of a coil antenna (Z-axis antenna). Accordingly, the battery holder 20 also serves as a member for winding the antenna wire of the third antenna 29 (Z-axis antenna), thereby reducing the number of parts and the size of the portable unit 100. Yes.

  In the laminate of the circuit board 10 and the battery holder 20, a power supply pin terminal 30 (connection pin) is inserted into each of the pair of pin terminal insertion holes 16 and 25 that communicate with the circuit board 10 and the battery holder 20. One end of the third antenna 29 is soldered to the tip of one power supply pin terminal 30 protruding to the battery holder 20 side, and similarly, the other end of the third antenna 29 is connected to the tip of the other power supply pin terminal 30. Is soldered. The tip of the power supply pin terminal 30 protruding toward the circuit board 10 is soldered to the terminal of the circuit board 10. Thereby, in the laminated body of the circuit board 10 and the battery holder 20, a structure in which a pair of power supply pin terminals 30 penetrates the battery holder 20 from the circuit board 10 in the thickness direction and connects them is configured. In addition, about the circuit board 10 side, the connector for pins may be provided, and the structure by which the work man-hour of soldering was reduced by it may be sufficient.

  Here, since the engraved portion 26 is formed in the battery holder 20 corresponding to the pin terminal insertion hole 25, the tip of the third antenna 29 is inserted by inserting the tip of the soldering iron along the engraved portion 26. The workability when soldering the wire to the tip of the power supply pin terminal 30 is excellent.

  In the laminate of the circuit board 10 and the battery holder 20, the pair of power supply pin terminals 30 connecting them has a straight line (broken lines in FIGS. 5A and 5B) connecting them in the plan view of the battery holder 20. The battery holder 20 is disposed so as to pass through the center of gravity G of the outer shape of the battery holder 20, that is, a position off the center of the holder. And the battery accommodating part 23 is provided in the gravity center G side of the external shape of the battery holder 20 rather than the straight line which connects a pair of electric power feeding pin terminal 30. FIG.

  Here, if the pair of power supply pin terminals 30 are arranged symmetrically so that the straight line connecting them passes through the center of gravity G of the outer shape of the battery holder 20, as shown in FIG. 20 is ideally superimposed on the circuit board 10 and is expected to be mounted in a balanced manner, but actually, the battery holder 20 floats away from the circuit board 10 as shown in FIG. As shown in FIGS. 7C and 7D, the battery holder 20 is inclined with respect to the circuit board 10 and is mounted with one side floating. However, according to the above configuration, in a plan view of the battery holder 20, the pair of power supply pin terminals 30 are arranged so that a straight line connecting them passes through a position away from the center of gravity G of the outer shape of the battery holder 20. Therefore, as shown in FIG. 8 (a), the battery holder 20 is subjected to a force to incline toward the circuit board 10 on the part of the outer shape opposite to the center of gravity G side, Since the battery accommodating part 23 is provided on the center of gravity G side of the outer shape of the battery holder 20 with respect to the straight line connecting the pair of connecting pins, when the button battery B is accommodated in the battery accommodating part 23, FIG. ), The force to incline toward the circuit board 10 is exerted on the battery holder 20 by the weight of the button battery B on the center of gravity G side of the outer shape of the battery holder 20, and these forces are offset. So that the result Stable mounting structure of the circuit board 10 of the battery holder 20 can be obtained.

  Further, when the button battery B is accommodated in the battery accommodating portion 23, the positive electrode terminal 15 forms an angle with respect to a straight line connecting the button battery B to the pair of power supply pin terminals 30 in a plan view of the battery holder 20. In addition, the battery holder 20 is configured as a biasing member that biases from the side in the direction of the center of gravity G side of the outer shape of the battery holder 20 (the direction of the arrow in FIG. 5A). And the component which is going to press the button battery B to the circuit board 10 side among this urging | biasing force bears the force which is going to incline to the circuit board 10 side which acts on the gravity center G side part of the battery holder 20. Thus, the battery holder 20 is assisted to obtain a stable mounting structure on the circuit board 10. In addition, by adjusting the urging direction of the button battery B by the positive electrode terminal 15, it is possible to control the balance of forces acting on the portion of the outer shape of the battery holder 20 on the center of gravity G side and the portion on the opposite side.

  In the laminated body of the circuit board 10 and the battery holder 20, when the button battery B is attached to the battery housing portion 23 of the battery holder 20, the button battery B is inclined and the first engagement against the bias of the positive electrode terminal 15. The button battery B is inserted so as to sink under the mating protrusion 24a, and the button battery B is engaged with the first engaging protrusion 24a. Subsequently, the button battery B is moved toward the circuit board 10 against the elasticity of the negative electrode terminal 14. It is only necessary to push in and release the force acting on the button battery B. At this time, when the force applied to the button battery B is released, the positive terminal 15 presses the button battery B against the inner wall 23a of the battery housing portion 23 from the side toward the second and third engagement protrusions 24b and 24c. In addition, since the negative terminal 14 urges the button battery B toward the opening side of the battery housing portion 23, the first to third engagement protrusions 24a, 24b, 24c are engaged with the button battery B. Thus, the button battery B is accommodated and held in the battery accommodating portion 23. When the button battery B is pressed against the inner wall 23a on the second and third engagement protrusions 24b, 24c side of the battery housing part 23 by the positive electrode terminal 15, the button battery B, the battery housing part 23, A gap is formed between the two.

  On the other hand, when removing the button battery B from the battery housing portion 23 of the battery holder 20, the nail or a thin protrusion is inserted into the gap between the button battery B and the battery holder 20 to resist the bias of the positive electrode terminal 15, That is, it is only necessary to apply a force from the side in such a direction as to eliminate the gap between the button battery B and the battery housing portion 23. At this time, the engagement of the second and third engaging protrusions 24b and 24c with the button battery B is released, and the button battery B is lifted from the battery housing portion 23 by the bias of the negative electrode terminal 14, and removed.

  Here, since the first engagement protrusion 24a is formed relatively large compared to the second and third engagement protrusions 24b and 24c, the button battery B is attached to the first when the button battery B is attached. They can be easily engaged by being inserted so as to be submerged under the engaging protrusion 24a. Further, the large first engagement protrusion 24a can also function as a mark indicating the insertion direction of the button battery B. Furthermore, after the button battery B is attached, the button battery B can be prevented from falling off by the large first engagement protrusion 24a. If the first engagement protrusion 24a is formed in a rectangular shape, the button battery B is more strongly fitted by the corners. However, if the first engagement protrusion 24a is formed in a disk shape as described above, the button battery B has an appropriate fit. Thus, the button battery B can be easily attached.

  Further, since the second and third engaging protrusions 24b and 24c are formed relatively small compared to the first engaging protrusion 24a, the button battery B can be easily removed.

  Furthermore, since the angle interval between the first to third engagement protrusions 24a, 24b, and 24c is 120 °, the button battery B can be stably accommodated and held in the battery accommodating portion 23 by the three-point support.

  The thickness of the laminate of the circuit board 10 and the battery holder 20 is defined by the protruding length of the power supply pin terminal 30, and the battery holder 20 includes the first to third engagement protrusions 24a, 24b, and 24c in the holder body. In the case of having a thickness, the thickness of the laminate of the circuit board 10 and the battery holder 20 is the sum of the thickness of the circuit board 10, the thickness of the battery holder 20, and the protruding length of the power feed pin terminal 30. However, when the battery holder 20 has a configuration in which the first to third engagement protrusions 24a, 24b, and 24c are integrally projected on the holder body, even if the thickness of the battery holder 20 is the same, for example, the holder If the protruding length of the power supply pin terminal 30 provided on the main body is shorter than the protruding lengths of the first to third engaging protrusions 24a, 24b, 24c, the thickness of the laminate of the circuit board 10 and the battery holder 20 is This is the sum of the thickness of the circuit board 10 and the thickness of the battery holder 20, thereby making it possible to reduce the thickness of the laminate.

  In the stacked body of the circuit board 10 and the battery holder 20, in a state where the button battery B is attached to the battery housing part 23 of the battery holder 20, the battery support part 23 b contacts the button battery B with the outer peripheral part of the bottom surface. Since it supports, it can prevent that the button battery B contacts the whole surface of the circuit board 10, and short-circuits. In addition, although the battery support portion 23b also contacts the circuit board 10, as shown in FIG. 9, the battery support portion 23b is formed in a U-shaped cross section that is open on the circuit board 10 side, so that the contact area with the circuit board 10 is small. Moreover, the mounting variation to the circuit board 10 of the battery holder 20 can be reduced. Further, the negative electrode terminal 14 is in contact with the center of the bottom surface of the button battery B, but since the interference prevention defect 23c is provided in the battery support portion 23b, the negative electrode terminal 14 is interposed between the battery support portion 23b and the button battery B. It is possible to prevent the button battery B from being inclined and attached to the battery housing portion 23 by being sandwiched. Further, the mounting state of the battery holder 20 on the circuit board 10 can be inspected by visually observing the positional relationship between the negative electrode terminal 14 and the interference prevention defect 23c. Note that a short circuit of the negative electrode terminal 14 to the wiring on the circuit board 10 can be prevented by an insulating film provided to cover the wiring.

  In the laminated body of the circuit board 10 and the battery holder 20, the inspection pins are simultaneously inserted into the aligned pair of inspection holes 17 and 28 to perform mass production inspection. The pair of inspection holes 17 and 28 are inspected. Since the inspection pins are guided, the variation in contact of the inspection pins with the circuit board 10 can be reduced, and the inspection pins are inserted into the pair of inspection holes 17 and 28 at the same time. Inspection can be performed.

  10A to 10C show the integrated member 40. FIG.

  The integrated member 40 is preferably formed of a material having elasticity such as a rubber material, for example, preferably a rubber material having a low dielectric constant in that the antenna performance is not deteriorated. Specific examples include EPDM (ethylene propylene rubber), fluorine rubber, HNBR (hydrogenated nitrile rubber), silicon rubber, and the like. Of these, silicone rubber is preferred from the viewpoint of transparency described later.

  The integrated member 40 is formed in a flat shallow dish shape, and is placed on the laminated body of the circuit board 10 and the battery holder 20 so that the battery holder 20 is exposed in the opening, covers the peripheral portion, and has a thickness. It is provided to fit in the direction. In the case of the integrated member 40 formed of a material having elasticity, when the integrated member 40 is fitted into the laminated body of the circuit board 10 and the battery holder 20, the opening of the integrated member 40 is elastically deformed to expand the mouth. After the external fitting, the laminated structure of the laminated body of the circuit board 10 and the battery holder 20 can be stably held by the elastic restoring force of the integrated member 40.

  Further, in the case of the integrated member 40 formed of an elastic material, the peripheral portion of the laminated body of the circuit board 10 and the battery holder 20 is covered and is externally fitted in the thickness direction. The structure of the unit 110 is simplified, and the integrated member 40 can be easily attached and detached when the parts are replaced. The integrated member 40 has, for example, a height (H1) of 7 mm to 9 mm and a thickness (t1) of 0.4 mm to 1.2 mm, preferably 0.6 to 0.8 mm. If the thickness of t1 is smaller than 0.4 mm, there is a risk of undesirably breaking when the mouth is expanded, and if it exceeds 1.2 mm, it is difficult to expand the mouth, and the external fitting process may be complicated.

  The integrated member 40 is provided with a fitting protrusion 41 on the inner side so as to correspond to the engraved portion 26 formed on the battery holder 20, and to correspond to the alignment mark 27 provided on the battery holder 20. In the opening end, for example, an isosceles triangular alignment projection 42 having an inward apex angle is provided. By fitting the battery holder 20 into the engraved portion 26 by the fitting protrusion 41 and aligning the battery holder 20 to the alignment mark 27 by the alignment protrusion 42, the circuit board 10 and the battery holder 20 of the integrated member 40 are aligned. Variation in mounting on the laminate can be reduced.

  The integrated member 40 is attached to a first case having a bottomed cylindrical shape opened to the covering side of the circuit board 10 and having a semicircular shape in plan view at the outer end at a position corresponding to the alignment protrusion 42 on the outer peripheral portion. The portion 43a is provided so as to protrude laterally. Further, the integrated member 40 has a bottomed cylindrical shape opened to the covering side of the circuit board 10 at an angular interval of 130 ° in the circumferential direction from the first case mounting portion 43a, and the plan view shape of the outer end is square. The second case mounting portion 43b is provided so as to protrude laterally.

  The integrated member 40 is preferably transparent at least at a portion covering the substrate surface of the circuit board 10. If the part of the integrated member 40 that covers the substrate surface of the circuit board 10 is transparent, a visual inspection can be performed with the integrated member 40 attached, and if a problem such as a short circuit occurs, for example. Since the portion is discolored, it is possible to easily identify the defective portion. The term “transparent” as used herein refers to a material having a degree of transparency or higher that allows visual confirmation of the presence / absence of components and discoloration of the circuit board 10 through the integrated member 40.

  The case 120 for accommodating the portable device unit 110 having the above-described configuration is attached to the first and second case members 121 and 122 formed in a shallow dish shape, for example, by ABS resin or the like, and the mounting pins P on the side surfaces thereof. For example, the strap holder 123 formed of ABS resin or the like is used. The case 120 is arranged such that the circuit board 10 side becomes the first case member 121 and the battery holder 20 side becomes the second case member 122 and the concave sides face each other, and the first and second case members 121 and 122 make the portable device. The unit 110 is accommodated so as to be sandwiched in the thickness direction. Therefore, the mating portion of the first and second case members 121 and 122 appears on the side surface of the case 120.

  The first case member 121 is provided with first and second unit mounting protrusions 121a and 121b so as to correspond to the first and second case mounting portions 43a and 43b of the integrated member 40, as shown in FIG. As shown, the first case mounting portion 43a is fitted on the first unit mounting projection 121a, and the second case mounting portion 43b is fitted on the second unit mounting projection 121b, whereby the portable unit 110 is mounted. It is fixed. Therefore, when the portable device unit 110 is used, the portable device 100 can be configured regardless of the shape of the case 120 as long as predetermined first and second unit mounting protrusions 121a and 121b are provided. . In addition, since the first and second case attachment portions 43a and 43b have different shapes from each other, workability when the portable device unit 110 is mounted on the first case member 121 is excellent.

  In the case 120, as shown in FIG. 12, the integrated member 40 has a portion that covers the outer peripheral portion of the surface of the circuit board 10 in contact with the inside of the first case member 121 and seals it, and a battery holder. A portion covering the outer peripheral portion of the surface of 20 is in contact with the inside of the second case member 122 for sealing. Therefore, since the inner part of the integrated member 40 is isolated from the outer part in the case 120, even if water or dust enters from the joining portion of the first and second case members 121 and 122, they are integrated. It can be stopped at the outer portion of the forming member 40, and water and dust can be prevented from reaching the inner portion of the integrated member 40 in which the circuit board 10 and the battery holder 20 are accommodated. That is, the integrated member 40 constitutes a waterproof / dustproof packing. As a result, the single integrated member 40 performs the two functions of integrating the laminate of the circuit board 10 and the battery holder 20 and waterproofing and dustproofing them.

  In addition, the shape of the circuit board 10, the battery holder 20, and the integrated member 40 constituting the portable device unit 110, the configuration of each part, and the configuration of the case 120 are not particularly limited to the present embodiment. Other configurations may be used. For example, as shown in FIG. 13, the integrated member 40 does not have a portion that covers the substrate surface of the circuit board 10, covers the periphery of the laminate of the circuit board 10 and the battery holder 20, and is externally disposed in the thickness direction. You may have an annular structure opened inside to fit.

  The present invention is useful for a portable unit and a portable device in which the unit is accommodated.
